mpc83xx: fix pcie enumeration
This patch fix a problem for the pcie enumeration for mpc83xx cpus. Without
this we will not get correct value in hose->regions[...].
The pointer *reg in function mpc83xx_pcie_init_bus() shall not be changed.
Because we will use this pointer as a parameter to call function
mpc83xx_pcie_register_hose().
